More Information

Overview Manuals Specifications Ethernet Ports Network Protocols Addressing Review

Features:

  • Dual Ethernet ports: Two RJ45 interfaces are provided for network connection.
  • Integrated switch: The two ports are connected through the module’s internal Ethernet switch.
  • Protocol support: ABB documents TCP/IP, UDP/IP, and Modbus TCP.

CM577-ETH adds Ethernet connectivity to an ABB AC500 configuration through two switched RJ45 interfaces.

Network engineering should document IP addresses, subnet design, Modbus TCP roles, port use, cable routing, segmentation, and permitted access.

Replacement planning should preserve the controller project and compare 1SAP170700R0001 with the installed module before any address changes.

Availability is subject to Apter Power's current inventory and sourcing confirmation.

Physical network review

  • Port count: Use the two documented RJ45 Ethernet interfaces.
  • Link speed: Plan for 10/100 Mbit/s operation within the connected network.
  • Internal switch: Account for the integrated switch when defining the physical topology.
  • Cabling: Verify connector condition, cable category, routing, and cabinet strain relief.

Communication planning

  • TCP/IP: Define addressing and permitted application connections.
  • UDP/IP: Document every UDP data flow used by the verified project.
  • Modbus TCP: Confirm client/server roles, register maps, and update timing.
  • Cybersecurity: Apply the site-approved segmentation and access controls.

Configuration preservation

  • Rotary switches: Record the installed address-switch positions before removal.
  • Project data: Back up AC500 configuration and communication parameters.
  • Device map: Preserve peer addresses, ports, registers, and expected diagnostics.
  • Acceptance test: Validate links and application data after controlled commissioning.
